Ukuthintela njani ukugcwala kwe-UV resin

I-Gelation ibhekisa kukuqina okanye ukufakwa kwe-resin ye-UV okanye ukwambathisa kwiqondo lobushushu elichaziweyo kunye nexesha.

Izizathu eziphambili ze-gelatinization ye-resin ye-UV okanye ukugquma zezi zilandelayo:

1. Ngaphandle kobomi beshelufu, ubomi beshelufu ye-UV resin phantsi kweemeko zogcino ezilungileyo abuyi kuba ngaphezu kweenyanga ezintandathu.Kodwa i-Z elungileyo inokusetyenziswa kwiinyanga ezintathu.

2. I-resin ye-UV kufuneka igcinwe kwimibhobho yeplastiki okanye kwimibhobho yentsimbi efakwe ngeplastiki.I-ion zetsimbi ziya kunciphisa amandla okuvula amabhondi aphindwe kabini kwi-resin ye-UV kwaye iqalise i-polymerization, ekhokelela kwi-resin gelation.Ke ngoko, ukuba umaleko weplastiki kwiplanga yeplastiki yonakele, umaleko wesinyithi ongenanto uya kubangela i-resin gelation.

3. Ubushushu bokugcina obuphantsi kakhulu (ngaphantsi kwe-0 ℃) buya kunyusa inhibitor ye-polymerization kwifilimu yepeyinti, okukhokelela kwi-resin self polymerization kunye ne-resin gelation.

4. I-resin ye-UV kufuneka ikhuselwe ngokungqongqo kwilanga elithe ngqo ngexesha lokugcinwa.Ngaphandle koko, kulula ukubangela i-resin gelation.

5. Ukuba umgqomo ugcwele kakhulu, akukho oksijini eyaneleyo yokukhusela i-polymerization, eya kubangela i-resin gelation.

Izilumkiso ze-gelation:

1. I-viscosity ye-resin ngaphandle kwe-diluting monomer iphezulu kakhulu.Abanye abasebenzisi baya kucinga ngempazamo ukuba i-resin ifakwe i-gelatinized.Enyanisweni, kulula ukubona ukuba i-resin i-gelatinized emva kokufudumeza.I-resin ngaphandle kwe-gelatinization iya kuba ne-fluidity enhle emva kokufudumeza.

2. Ngokuphathelele ukusetyenziswa kwe-resin ye-UV, iindlela zokubona kunye nezibonakaliso zefilimu yokugqoka i-UV zifana nezo zezinye iingubo, ezihluka kunye nesicelo esithile.Kuya kubakho iingxaki ezahlukeneyo ekusetyenzisweni kweengubo ze-UV.Kuphela i-gelatinization ngexesha lokugcinwa ihambelana ngokusondeleyo ne-resin ye-UV ngokwayo, kunye nezinye iingxaki zingasombululwa ngokuhlengahlengisa ifomula yokugqoka i-UV.Njengoko i-uvpaint yenziwe ngamacandelo ahlukeneyo, ikwachatshazelwa ngumgama wokukhanya komthombo wokukhanya kunye nexesha lokukhanyisa, kwaye ukusebenza kwayo kwefilimu kusisiphumo sesenzo esibanzi sezinto ezahlukeneyo.Kwifomula efanayo, ngokukhawuleza buyisela i-resin efanayo.Ngenxa yokungafani kwee-resin ezivela kubakhiqizi abahlukeneyo, ukusebenza kwefilimu kuya kutshintshwa, kwaye ifomula kufuneka ilungiswe.Nangona kunjalo, ngokude nje i-resin ayinayo i-gelatinized okanye i-gelatinized kwipeyinti elungiselelwe, ukusebenza kwefilimu kunokulungiswa ngefomula.

3. Kukho izizathu ezininzi ze-gelatinization yepeyinti ye-UV, engahambelani kuphela ne-resin.Okokuqala, kufuneka sijonge ukuba ingaba ibangelwa kukugcinwa okungafanelekanga.Ngenxa yokongezwa kwe-photosensitizer kwi-UV yokugquma, iimeko zokugcina zayo zingqongqo ngakumbi kunezo ze-resin ye-UV.Kuyimfuneko ukuyigcina ebumnyameni ukuphepha ukubona ukukhanya.Okwesibini, i-photosensitizer ekhethiweyo ikumgangatho ophantsi, kwaye nokuba igcinwe ebumnyameni, iya kubola kancinci kwaye ibangele i-gelation yokwaleka okunyangayo.

4. Umgangatho we-monomer nayo yinto ebalulekileyo echaphazela ukuzinza kokugcinwa.
